摘要
针对目前的电力系统继电保护装置无法很好地解决励磁涌流对变压器纵联差动保护的影响,本文通过对变压器空载投入时产生励磁涌流的现象进行分析和仿真。通过仿真软件分析励磁涌流的产生条件和对电网的影响,比较在不同的条件下励磁涌流的变化情况。为变压器纵联差动保护的进一步发展具有实际意义。
In view of the current power system relay protection device can not solve the effect of inrush current on transformer longitudinal differential protection,this paper analyzes and simulate the phenomenon of inrush current when the transformer is unloaded. Simulation software is used to analyze the excitation inrush current and the influence on the power grid,and compare the variation of magnetizing inrush current under different conditions.It has practical significance for further development of transformer longitudinal differential protection.
